![]() ![]() And so we can really justĬompare the numerators. Out just to make sure I didn't make a mistake. The numerator by 28 if we don't want to change So what is 21 times 9? That's easier toĭo in your head. So I'm saying theĬommon denominator here is going to be 252. In your head 28 times 10, which would be 280,Īnd then subtract 28 from that, which would be what? 252. Multiple of 28 and 9 have to contain a 2,Ī 2, a 7, a 3 and a 3. So what's the primeįactorization of 28? It's 2 times 14. ![]() So we could just findĪ least common multiple in the traditional way With- if we didn't think to simplify ourĬolor I haven't used yet. Greater than- and 8/12 is the same thing as 6/9- isĭefinitely greater than 6/9. Same thing as 21/28, we could say 21/28 is definitely 21/28 is the exactĪ greater quantity? Well, clearly, we have the And so now when weĬompare the fractions, it's pretty straightforward. So we're multiplying theĭenominator by 3 to get to 12. And either way youĭenominator for 4 and 3. And 3- it's alreadyįactorize it any more. Another way you couldįactorization, is 2 times 2. And we can write 2/3Īs something over 12. So their least commonĪs something over 12. ![]() The common denominatorĬommon multiple of 4 and 3. Then we would have toįairly small numbers. And the real benefit ofĭoing this is now this is much easier to find a commonĭenominator for than 28 and 9. The greater than symbol is placed between two values where the number to the left of the symbol is greater than the number to the right of the symbol. Them both by 3 so we can simplify this fraction. ![]() So 21 divided by 7 is 3,Īnd 28 divided by 7 is 4. 3 comments ( 17 votes) Upvote Downvote Flag more Show more. fractions can also be turned into decimals, so 3/7 3 divided by seven, which is about 0.4285. Thing to the numerator and the denominator, Below are six versions of our grade 4 fractions worksheet on comparing (greater than, less than, equal to) proper and improper fractions with mixed numbers. If you have a bigger denominator it is smaller because then you have more parts, and that makes it smaller. So let's divideīoth the numerator and the denominator by 7. Last one, because I have a feeling that'll be Simplify them first and then try to do it. So what we could do is weĬan find a common denominator for both of them and convertīoth of these fractions to have the same denominatorĪnd then compare the numerators. To compare fractions, all you have to do is to make it so that they have the same denominator and then see which fraction has the greater numerator - this. Had the same denominator, you could just compare Greater than, or equal to compare the two fractionsĢ1/28, or 21 over 28, and 6/9, or 6 over 9. If you are still having trouble, here are some videos that may help: Students with learning differences like dyscalculia may have an especially hard time with this skill. They often have trouble figuring out if one fraction is greater than, less than, or equal to another fraction. The greatest common factor of 24, 42, and 60 would be 6 because the largest number that fits into 24, 42, and 60 is 6. Comparing fractions can be hard for many elementary students. The least common multiple of 4, 5, and 6 is 60 because the smallest number that 4, 5, and 6 fit into is 60.Ī highest common factor (HCF) usually called the greatest common factor is the largest number that all numbers of a set are divisable by:įactor - Can fit evenly into those numbers Multiple - Evenly divisible by those numbers Figure out the two fractions and determine if one is less than, greater than, or equal to the other. For instance:ħ is a whole number because the only whole numbers that fit into 7_ is 1 and 7.Ħ, however, is _not a prime number because both 2 and 3 fit into 6 as well.Īny whole number that is not a prime number is called a composite number.Ī least common multiple (LCM) is the smallest number that all numbers of a set fit into:Ĭommon - Shared by all of the numbers in a set So, the fraction with the smaller denominator is actually the bigger fraction.Prime numbers are whole numbers that are only divisible by 1 and itself. Which is greater 1/2 or 1? 1 > 1/2 1/2 1/2 One written as a fraction looks like 1/1ĥ Which is greater 1/4 or 1/2? 1/4 1/4 1/8 1/8 1/4 1/8ħ Which is greater 1/8 or 1/2? 1/8 1/8 1/ /8 1/6ĩ Which is greater 1/2 or 1/6? 1/6 1/2 > 1/6 1/6 1/2 1/6ġ0 Which is greater 1/5 or 1/10? 1/10 1/5 1/10 1/5 > 1/10ġ1 When the numerators are the same, all you have to do is look at the denominator.īigger denominators mean the size of the pieces the whole has been divided into are smaller.
